143
53
286
573
Answer:
143
Explanation:
Using one of the 3 fundamental equations in physics, y=vo*t+1/2gt^2, we can use this equation to find the total distance that was traveled.
Acceleration due to gravity is always 9.8m/s^2 and time is 5.4s, we also have no initial velocity.
Given this, we can plug in the known variables.
y=0t+1/2*9.8*5^2
simplify,
y=4.9*5.4^2
y=4.9*29.16
y=142.884m which we can round up to 143 meters
Final Answer: 143 meters

A bicyclist with a mass of 50 kg is traveling at a rate of 30 m/s. It accelerates to a rate of 50 m/s in 5 seconds. What is the net force acting on the bicycle?
Answer:
200 N
Explanation:
There is only two needed factors in play here; the mass and acceleration
According to Newton's 2nd Law: F = m*a
Now Acceleration is Velocity over Time, so we have another factor in play: Acceleration = 50-30/5 = 20/5 = 4m/s^2
Net force = (50 kg)(4 m/s^2) = 50*4 = 200 Newtons

Hello!
[tex]\large\boxed{800Ns}[/tex]
Remember that impulse is equivalent to:
Impulse = force (N) × time (s)
Plug in the given force and time:
Impulse = 25 × 32
Impulse = 800 Ns

Answer:
Acceleration & 9.8 M/S/S
Explanation:
Pretty self explanatory for question 2, speeding up can easily be related to acceleration, and for question 3
"Its value is 9.8 m/s2 on Earth. That is to say, the acceleration of gravity on the surface of the earth at sea level is 9.8 m/s2. When discussing the acceleration of gravity, it was mentioned that the value of g is dependent upon location. There are slight variations in the value of g about earth's surface."

Discuss the difference between short-term and long-term fitness goals. Provide an example of each
Answer:
. A long-term goal is a goal set for you to achieve with 3-5 years, while short-term goals take a few days, weeks, or maybe months. An example of a short-term is eating like less carbs. An example of a long-term running like a 5k marathon.
what is a gram used to measure
Answer:
The gram is the basic unit of measurement
Explanation:
You use it to weigh small items such as sugar, flour, coffee, and other items that are similar.
If you want to measure in grams using a scale is the most accurate solution.

Is it true that acceleration occurs when there is a change in speed
Answer:
Acceleration is the rate of change of velocity.
Explanation: For example, acceleration is measured in m/2^2 or meters per second squared. That can also be split up into 2 components. M/s is how speed is measured, and since acceleration is the rate of change of velocity, m/(s*s). You could say that since acceleration is m/s^2, it can also be represented as how much the speed increases over 1 second. if there was an acceleration of 3 m/s^2, the rate of change of speed would be 3m/s every second, meaning that the object would speed up 3m/s every second that passes by.
Hope this helps!

Thomas found an organism in his backyard and is trying to classify it into a kingdom. The organism has small roots, and Thomas found it in moist soil with lots of decaying matter. He cut a piece off and put it under a microscope. The piece is multi-celled with nuclei and has cell walls composed of chitin. Which kingdom does Thomas' organism most likely belong to?
Answer:
Kingdom Plantae
Explanation:
Plants are multi-celled, have roots, and are found in the backyard. I also did research but I can't put it in here or else my answer gets deleted. :)

A duck is floating in a pond. How does Archimedes' description of the buoyant force explain why the duck
doesn't sink?
PLEASE HURRY
Answer:
The upthrust or buoyant force helps the duck doesn't sink.
For example, there is a duck which weighs 3 pounds and tree pints of water also weigh three pounds. In this case the volume of the duck is more than the volume of three pints of water, so the duck floats.

A weightlifter completes a series of lifts with a 700 N weight. In one lift, he raises the weight to a height of 2.5 m off the ground. The lift takes 0.60 s to complete. What power does the weightlifter have been performing this lift
Answer:
The output power the weightlifter is 2916.67 W.
Explanation:
Given;
weight lifted, W = 700 N
height the weight is lifted, h = 2.5 m
time taken to lift the weight, t = 0.60 s
The output power the weightlifter is calculated as;
Power = Energy applied / time taken
Energy applied = weight lifted x height the weight is lifted
Energy applied = 700 x 2.5
Energy applied = 1750 J
Power = 1750 / 0.6
Power = 2916.67 J/s = 2916.67 W.
Therefore, the output power the weightlifter is 2916.67 W.
